[en] Purpose: The objective was to determine the psychometric properties and the clinical application of a new Quality of Life self-assessment questionnaire suitable for adolescents 13 to 18 years old: the “Inventaire Systémique de Qualité de vie pour Adolescents” (ISQV-A).
Methods: This was a cross-sectional validation study. 171 French adolescents have completed the ISQV-A. Other tools were used: the State-Trait Anxiety Inventory for Children (STAIC), the Children’s Depression Inventory (CDI).
Results: The internal consistency of the four indices of the ISQV-A (state, goal, rank and gap) is satisfactory. All scores have their own specificity. The data show the convergent validity, test-retest fidelity and applicability of the ISQV-A.
Conclusions: The adequacy of this new tool seems evident to highlight the adolescent’s quality of life. We will also discuss its clinical relevance into a cognitive behavioural approach.
